MEANS FORlDELIVERING NIESURED QUANTITIES OF LIQUID.

Patented April 3o, 1907.

Application led December 29, 1906. Serial No. 349,988.

To LZZ whom it' may concern:

. and I do hereby declare the following to. be a tected from injury.

full, clear, and exact description of the invention,- such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide in or foreombination with a can or `vessel, means for delivering measured quantities of liquid from it at will. When desired the number oi' quantities for example, pints, delivered will be indicated by having a counter attached. The invention is. intended for, among other iluids, milk, and it has been so arranged that the parts can easily be dissem- Lbled, inspected and cleansed. The operation of the measuring device is rapid, and the working parts are so positioned as to be pro- All that it is necessary for the milkman or user to do when he desires to delivel a charge-say one pint-is press a but ton or lever so as to raiseI a spindle which operates two valves in turn-as is described below. Then when the button is released the measuring vessel refills and is ready or the next delivery. Y

The invention is illustrated in the drawings herewith which show a can 'which maybe carried by a milkman, instead of an ordinary one, and by which he can deliver without yintroducing a measure into the iluid or even removing the can lid.

Figure I is a side elevation in central middle section; Fig. 2-is a plan view from above the can when the lid is removed.. Fig. 3 shows in,.plan view a detached detail.

In these drawings a indicates the can, b its base or lower rim, c its bottom, which is higher than b, and d is an aperture in c, the whole constructed to form a storage chamber and a valve controlled communicating measuring chamber. A stem or spindle e suitably supported passes through the said aperture and carries two slidable valves f and g, both being loose on the spindle but limited as to the distance of their movability along the same. The former is shown open, the latter dlosed, spring pressure being utilized for this purpose. Valve f controls aperture d which lis at the top of a measuring chamber r, and

valve g controls the outlet `from that chamber at the latters base.

Z'is an upper bracket or.support of the stem or rod e, and of a lever for lifting the said rod; m, 'm1 are projections or collars suitably secured to that rod removably or adjustably in some cases; and n a spring abutting against parts l and m and normally pressing down rod e, keeping valvef open, so that ehamber 7c is normally always full.

o is a stop fixed to stem e. This stop may be a rod or be tubular it is located between valves f and g, leaving a gap p between its upper end and-valve j. The lower end o1 of part o is the part of 1t which is shown fixed to spindle e, but instead of said end a collar or other abutment could be used. A spring g abuts against part o1, and against valve f, being so placed as to require further compression to bring the two valves closer than their normal position.

h shows the outlet or nozzle of measuring chamber k vwhich has a bottom i removably secured in position as by being screwed on as at k1, and having if desired a ilange il to press against a washer j to prevent leakage.

r represents any suitable washer to prevent leakage of valve g, and s a similar washer to prevent leakage of valve t is an air pipe extending any suitable height from chamber k. The air pipe top is protected from dust as by the can lid u.

o is a lever suitably pivoted, as at w to bracket Z, and connected or pivoted to rod e, as at the lever head or button y being adapted to be pressed down by the milkman or other user, causing the raising of rod e and the striking of a shoulder or projection z at the base thereof against the valve g or a ange thereon. Acup i? in the bottom 'i by being pressed against by the washer r or valve under side, prevents leakage by way of the stem foot z.

A hinged or other cap y1 is when desired used on lid 'u to cover button y and thus exclude 'dust from vessel a.

When rod e with valve f kept up by spring rises that valve closes aperture d after which ange a contacts withy and raises valve g, which prior to the said contact is kept down on its seat by the weight of liquid on it.

When valve g opens, the liquid in vessel le escapes, and is at will delivered to any suitable receiver, no 'other liquid being able mean,

while to 'enter vessel lc. VWhen valve g .is opened fully the topot stop o meets valve f. When raised rod e is allowed te descend to its normal position, the pressure for atirne of the compressed spring g on valve f keeps that valve closed (collar m1 being meanwhile .raised out of contact with the said valve); valve g however descends since the lowering of part z allows the latter valve to fall to its seat by its own weight. Then collar m1 contacts with the flange f 1 of valve f (and as rod e descends. to its normal position by the pres-v sure of spring n) forces valve o en, against the powerof spring g. ln this 1t is assisted by the weigh-t of any liquid in can a. W hat l do claim as my invention and desire-to secure by Letters Patent of the United States is l. The combination with a can, comprising a storage chamber and a communicating measuring chamber, provided with any outlet, of a reciprocating spindle assing through said chambers, a valve loose y mounted on said spindle adjacent said outlet and no r-v mally closing said outlet, a valve loosely mounted on said spindle at the upper endof -said measuring chamber and normally main-- taining open communication between said storage chamber and said measuring chamber, and means cooperating with said spindle Vandl valves toinitially close said upper valve against its seat upon the upward movement o said spindle and upon continued upward movement to raise said lower valve from .its seat, and upon the returnmovement of said spindle to initially close said lower valve on its seat before opening communication between said storage and measuring chambers, substantially as described. Y

2. The combination with a can comprising a storage and measuring chamber, an outlet being provided for said measuring chamber, and ay communicating passage being formed between said measuring chamber and said storage chamber, of a spindle passing through said chambers, a valve oosely mounted" on said spindle and cooperating with said outlet, a second valve loosely -mountedI on said spindle at the upper end of' said measuring chamber, a spring interposed between said valves for normally supporting said u per valve in its open position, means carried3 by said spindle engaging said lower valve during the upward movement of said indie, and means for reciprocating said spinlil e, substantially as described.

The combination with a can comprising a storage chamber and a communicating measuring chamber provided with an*outlet,-

of a spindle passing through said chambers,v

an outlet valve loosely mounted on the lower end of said spindle, an upper valve loosely mounted on said spindle at the upper end ofsaid measuring chamber, a stop securedto said spindle between said valves, and springs interposed between said stop and upper 7o and means carried by the lower end of said valve., means for reciprocating said spin( measuring chamber provided with an outlet,

of a reciprocating spindle passing through said chambers, `an outlet valve loosely mounted on said spindle at its lower end, an up 'er valve loosely mounted on said spindle an( provided with a boss, abutmentsv carried by said spindle above said upper valve, the lower one of said abutments cor'perating with said boss, substantially as described,I a spriig engaging said upper abutment and. a rlgi spind e comprising a cy indrical hollow member disposed-'between said valves, a springfcontained within said hollow stopy and partv of said can, a sto secured to said normally supporting said upper valve in its open position, and a stop Carried at the lower end of said. spindle for engaging said outlet valve at a predeterminedposiltion in the upward stroke oi said spindle, and a lever pivotally connected to said spindle, substane tially as described.

5. The combination with a can comprising a storage chamber and a measuring chame ber, said measuring chamber being provided with an outlet consistingof a' base member IOO having an upwardly extending cup formed thereon and forming with theupper edge of said base member a valve seat, ofa reciproeating s indle extending through said chambers an( disposed atfits lower end in said cup member, a valve loosely-mounted on said spindle, ada ted to be normally seated on said cu an( base member, means for opening an closin` communication between said chambers, an( means for reciprocating said spindle, substantially as described..

In witness whereof l have hereunto set my hand in the presence of two witnesses.
